wattage rating. Induction motors, as well as some televisions, may
require 2 to 6 times their wattage rating to start up. The most demand-
ing in this category are those that start under load, such as compressors
and pumps. Testing is the only definitive way to determine whether a
specific load can be started and how long it can run. The unit will simply
shut down if it is overloaded. To restart the unit after a shutdown due to
overloading, momentarily turn off the power to the unit.
CAUTION:
This inverter will not operate high wattage appliances or
equipment that produce heat, such as hair dryers, microwave ovens,
and toasters.
4.2 BATTERY OPERATING TIME
With a typical vehicle battery, a minimum operating time of 2 to 3 hours
can be expected. In most instances, 5 to 10 hours of operating time is
achievable. However, Vector recommends that the operator start the
vehicle every 2 to 3 hours to recharge the battery system. This will guard
against any unexpected shut-down of the equipment and will ensure
that there is always sufficient battery capacity to start the vehicle's
engine. The inverter will sound it's alarm when DC voltage drops to
10.6V.
The inverter may be used whether or not the vehicle's engine is running.
However, the inverter may not operate while the engine is starting since
the battery voltage can drop substantially during cranking.
The inverter draws less than 0.3 ampere from the battery when it is not
supplying power to a load. In most instances, the inverter can be left
connected to the battery when not in use since it draws so little current.
However, if the vehicle is to remain unused for several days, disconnect
the inverter from the battery.

PROTECTIVE FEATURES OF THE INVERTER
Your Power-On-Board™ 400 monitors the following potentially hazard-
ous conditions:
Low Battery Voltage - This condition is not harmful to the inverter but
could damage the power source. An audible alarm will sound when
input voltage drops to 10.6. The Power-On-Board™ 400
automatically shuts down when input voltage drops to 10.0 volts. When
the condition is corrected, the unit may be restarted.
